SPECIFICATION forming part of Letters Patent No. 331,757, dated December 8, 1885.

Application filed February 14, 1885. Serial No. 155,953. (No model.)

To @ZZ whom, t 77mg/ concern.-

Beit known that I, LUTHER C. BALDWIN, of Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Apparatus for Painting Bobbins and other Like Articles, of which the following is an exact description.

Said articles in their manufacture require to be painted on their ends, and in many cases they are painted over their entire surface. For painting such articles neatly and automatically I have invented this machine.

Reference is to be had to the accompanying drawings, which form part of this specication.

Similar letters indicate similar parts in all the gures.

Figure lis a top View of the machine. Fig. 2 is a vertical section of the entiremachine on the line of the driving-shaft G, drawn on a larger scale. Fig. 3 is a perspective view of one of the spindles and its support when detached from the machine.

A represents any suitable support, upon which is fastened the table B, which supports the boxes b b, in which turns the drivingshaft C.

Upon the table B is lined an upright shaft or post, D, upon which turns a sleeve, E, carrying the disk F upon its upper end, and having the bevel-gear G fixed upon its lower end. Upon the diskF at intervals, radiating from its center and projecting beyond its circumference, are placed spindles or mandrels m, held in position by the supports H, which are fastened to the disk F by a suitablehinge, h, in such manner that when the inner end of said support is depressed by means of the camplate a the outer end, together with the projecting spindle 'ms inclined upward and outward,so that the bobbins or other articles may be more easily placed thereon or removed. The spindles m are provided with pulleys p, the object of which will be hereinafter shown. Upon the sleeve Eturns a similar sleeve, I, to which is fastened the disk J, provided with annular ilanges c and d,which project upward near the circumference of said disk, and in such position that when the spindles m rest in a horizontal position the pulleys p rest upon the edge of the flange d,while the edge of the the arrangement of theA gearing the disk J turns the faster, and the frictional contact of the flange c with the bobbin or other article e rotates said article upon its spindle or mandrel m, which also is rotated in the same direction by the contact of the inner dan ge, d,w1th the pulley p, thus avoiding any friction which the article e would encounter if the spindle remained fixed.

Either of the iianges c or d is removable, and the bobbins, or other articles may be tted tightly upon the inandrels m and rotated, together with said mandrels, by the action ofthe inner ange, d, upon the pulleys p, or they may be fitted loosely upon said mandrels and rotated upon them bythe contact ofthe outer ange, c, with said articles, as hereinbefore shown, said spindles or mandrels remaining Xed in their supports. The working edges of the annular flanges c and (l may be serrated in order that they may more surely andleasily turn the bobbins and spindles.

'While being rotated by one or both of the flanges c and d, as hereinbefore described, the bobbins or other articles are carried by the revolving disk or table F over and in contact with a mechanically driven rotary paint-brush, g, the lower circumference of which dips in a receptacle containing paint or varnish, while the upper circumference touches the articles to be painted as they pass. :Said articles are held firmly against the brush g by the presser P, which is fastened to the post D by the collar and set-screw The outer end of said presser bears upon the-ends of the spindle-supports and holds them down upon the table F while they pass the brush. After being painted, the continued revolution of the table F brings the inner ends of thespindle-supports under the cam-plate a, which is fastened to the post D and inclined downward in the direction of the revolution of the disk or table F. The inner ends of said spindle-supports are IOO forced downward by said cam-plate through apertures made in the table F, and their outer ends are raised correspondingly, as shown in Fig. 2. While in this position the bobbins or other articles may be easily removed and replaced by others.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In apparatus for painting bobbins and other like articles, the mechanically-driven table F, turning upon a central post, D, and provided with one or more work-carrying spindles, m m, as and for the purpose set forth.

2. In machines for painting bobbins and other like articles,the disk J provided with one or both the annular flanges c and d, arranged to rotate the work while being painted, sub stantially as shown.

3. In an apparatus for painting bobbins, the work-carrying spindles mm, provided with frictionpul1eys p, and supported by the frames H, said frames being so hinged that by depressing their inner ends said spindles may be inclined upward and outward, as described, and for the purpose set forth.

after they have been painted. 4o

6. In an apparatus for paintingbobbins, the combination ofthe revolving table F, the workcarrying spindles m, the disk J, provided with the work-rotating ianges c and d, a device, l?, for steadying the bobbins While being painted',` the brush g, and a device, a, for inclining the spindles upward and outward, all substantially as specified, and for the purpose set forth.
